Perform histogram equalization for the following histogram.
| Gray level | 0 | 1/7 | 2/7 | 3/7 | 4/7 | 5/7 | 6/7 | 7/7 |
| Number of occurrences | 400 | 700 | 800 | 900 | 500 | 400 | 196 | 200 |
Given an image with uniform histogram. Explain the effect of applying following compression techniques:

ii) Golomb,
iii) LZW,
iv) Prediction coding, and
v) Optimal Quantization
Explain in detail the adaptive mean and median filters.
b) Obtain mean and variance of the following noise pdfs:
i)
ii)
iii)
) Given an image f(x,y) with Fourier transform F(u,v) obtain the fourier transform of .
c) Given that the 2-D Fourier Tranform is real and even, obtain the constraints on the image characteristics.
) Propose a gray level slicing algorithm capable of producing the 4-bit plane of an 8-bit monochrome image.
Filter the given gray level image with
i) mean filter using zero padding
ii) 3×3 weighted mean filter using zero padding with mask
iii) 3×3 median filter processing only such pixels that have all the needed neighbours.
iv) Laplacian filter with the given mask and reflecting the border pixels.
Describe the homographic filtering. Explain why the filtering scheme is effective for the applications it is used.
